Lets start with baptismal records.
On the page Julliane marked:
1: Go to Indeks for baptismal records part
Find your family member under the year and surname.
This will give you the place of birth - book number and page for the entry you are looking for.
Make a list of all and send me a private messages with this information and I will send you the links to the baptismal records if they are available.
Go to the National Archives of South Africa part Click on New Nairs.
Enter your information in the search box and look at all the entries until you find your family. Now- watch the Video Mathew made. and you are set to find your family members. Part of the Death Notice sometimes contain other information as well so do page and see what is on offer.
I will send you a private list of all the links should you need them. Just send me a private message please.
